Features:
- Axis 3 gearbox and is verified against the exact ABB hardware marking and installed configuration before replacement.
- TS225R identity and is verified against the exact ABB hardware marking and installed configuration before replacement.
- Legacy original design configuration and is verified against the exact ABB hardware marking and installed configuration before replacement.
ABB identifies 3HAC031074-004 as the axis 3 reduction gearbox for the IRB 4600. The listed configuration uses the TS225R gearbox with a documented reduction ratio of 137 and belongs to the Legacy original design arrangement. Ordering must follow the complete article number because neighboring ABB gearbox versions can differ in reduction, mounting design, supplier configuration or robot application. The installed gearbox identity and robot serial data should therefore be compared before replacement.
Before replacing 3HAC031074-004, record the installed position, hardware revision, mounting or connector arrangement, paired assemblies and every applicable ABB service record. Compare the supplied unit with the original item and approved configuration, isolate all relevant energy sources, and follow the documented installation procedure. After installation, inspect every affected mechanical, electrical and communication interface and complete controlled functional checks before returning the equipment to service.
The 3HAC031074-004 ABB Robot joint drive gearbox is listed as Active / Available from OEM. Current revision, availability and supplied scope are confirmed in the written quotation.
ABB 3HAC031074-004 documentation and reference links.
Important Notice: Every linked document must identify the listed model or its documented family. Confirm the complete order code, hardware revision and installed-system requirements before replacement.
3HAC031074-004 should be identified by the complete ABB article number together with IRB 4600, axis 3 and legacy original design data. The installed TS225R nameplate and robot serial record provide the primary order-stage evidence.
The documented configuration uses TS225R at a 137 reduction ratio. Do not select a neighboring gearbox solely from external appearance; confirm the ABB design identity and mechanical configuration first.
Before replacement, preserve robot and gearbox identification, follow ABB mechanical and lubrication instructions, and plan the required calibration checks. Accessories, service tools and consumables should be confirmed separately for the actual maintenance scope.
